Could not install JAR error 7515

I followed the tutorial below in order to create a simple Java UDF for Teradata. Simple Java UDF The problem that i am facing is when i try to deploy the JAR to the database server . I am getting the following error:

Simply check the Messages manual:
7515 Unable to create new DLL for the UDF/XSP/UDM.
Explanation:
The system was not able to create the new DLL for the UDF/XSP/UDM. In general this should not occur. It could be caused by either for a bad path to the UDF/XSP/UDM library directory or the directory has no space available. This is a system disk directory NOT part of the database.
Generated By:
AMP subsystem.
For Whom:
DBA.
Remedy:
The remedy is to make sure the UDF GDO configuration paths are pointing to a valid directory(s). Also make sure the directory has enough space to hold a UDF/XSP/UDM DLL (DLL: Dynamic Linked Library).

You may want to make sure the class / jar file are compiled to be compatible with the JRE bundled with Teradata.

Apache Commons Daemon specify classpath

I try to deploy a program as windows service with apache commons daemon. i have everything set up fine beside the classpath.
Classpath=C:\test\test-service\lib\*
specifies where the service itself lies, but the service needs some configuration files to run and these are under
Classpath=C:\test\test-service\conf\*
now i struggle to get it to work so that the program uses C:\test\test-service\* as classpath and not just one of the both specified above. sadly C:\test\test-service\* does not work and throws a ClassDefNotFoundException for the starter class. that error is solved by C:\test\test-service\lib\* but then i get the error that my config files can't be read. therefore i thought, why not also add the config path to the classpath like this:
Classpath=C:\test\test-service\lib\*;C:\test\test-service\conf\*
but this still throws the FileNotFoundException. does anyone has a solution to this?

So I was able to solve this by myself. Following works:
Classpath= C:\test\test-service\conf\;C:\test\test-service\lib\*
it takes all files in conf folder by default as well as all files from lib as the * states

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver ubuntu? [duplicate]

There is a VERY similar question to mine but in my case I don't have any duplicate jars in my build path, so the solution does not work for me. I've searched google for a couple of hours now, but none of the solutions I've found there actually resolve my issue. I'm creating a web site with some database connectivity for a homework. I'm using a MySQL database, developing in Eclipse and running on Windows.
I keep getting java.lang.ClassNotFoundException: com.mysql.jdbc.Driver with the following code:
import java.sql.*;
//...
public void someMethodInMyServlet(PrintWriter out)
{
Connection connection = null;
PreparedStatement query = null;
try {
out.println("Create the driver instance.<br>");
Class.forName("com.mysql.jdbc.Driver").newInstance();
out.println("Get the connection.<br>");
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "secret");
query = connection.prepareStatement( "SELECT * FROM customers");
//...
} catch (Exception e)
{
out.println(e.toString()+"<br>");
}
}
//...
When I run the above code I get the following output:
Create the driver instance.
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
It doesn't get past the Class.forName... line and I can't figure out why! Here is what I did:
Download mysql-connector.
Put it in my MySQL folder C:\Program Files\MySQL\mysql-connector-java-5.1.12\mysql-connector-java-5.1.12-bin.jar.
Opened the project properties in Eclipse.
Add External Jar to my Build Path and I selected mysql-connector-java-5.1.12-bin.jar.
Every time I attempt to use the servlet I get the same error regardless if I have the jar in there or if I don't. Could you help me figure this out?

As for every "3rd-party" library in flavor of a JAR file which is to be used by the webapp, just copy/drop the physical JAR file in webapp's /WEB-INF/lib. It will then be available in webapp's default classpath. Also, Eclipse is smart enough to notice that. No need to hassle with buildpath. However, make sure to remove all unnecessary references you added before, else it might collide.
An alternative is to install it in the server itself by dropping the physical JAR file in server's own /lib folder. This is required when you're using server-provided JDBC connection pool data source which in turn needs the MySQL JDBC driver.

How should I connect to JDBC database / datasource in a servlet based application?
Where do I have to place the JDBC driver for Tomcat's connection pool?
JDBC CLASSPATH Not Working

Since you are running it in servlet, you need to have the jar accessible by the servlet container. You either include the connector as part of your application war or put it as part of the servlet container's extended library and datasource management stuff, if it has one. The second part is totally depend on the container that you have.

The others are right about making the driver JAR available to your servlet container. My comment was meant to suggest that you verify from the command line whether the driver itself is intact.
Rather than an empty main(), try something like this, adapted from the included documentation:
public class LoadDriver {
public static void main(String[] args) throws Exception {
Class.forName("com.mysql.jdbc.Driver");
}
}
On my platform, I'd do this:
$ ls mysql-connector-java-5.1.12-bin.jar
mysql-connector-java-5.1.12-bin.jar
$ javac LoadDriver.java
$ java -cp mysql-connector-java-5.1.12-bin.jar:. LoadDriver
On your platform, you need to use ; as the path separator, as discussed here and here.

Place mysql-connector-java-5.1.6-bin.jar to the \Apache Tomcat 6.0.18\lib folder. Your problem will be solved.

What you should not do do (especially when working on a shared project)
Ok, after had the same issue and after reading some answers here and other places. it seems that putting external lib into WEB-INF/lib is not that good idea as it pollute webapp/JRE libs with server-specific libraries - for more information check this answer"
Another solution that i do NOT recommend is: to copy it into tomcat/lib folder. although this may work, it will be hard to manage dependency for a shared(git for example) project.
Good solution 1
Create vendor folder. put there all your external lib. then, map this folder as dependency to your project. in eclipse you need to
add your folder to the build path
Project Properties -> Java build path
Libraries -> add external lib or any other solution to add your files/folder
add your build path to deployment Assembly (reference)
Project Properties -> Deployment Assembly
Add -> Java Build Path Entries
You should now see the list of libraries on your build path that you can specify for inclusion into your finished WAR.
Select the ones you want and hit Finish.
Good solution 2
Use maven (or any alternative) to manage project dependency

Just follow these steps:
1) Install eclipse
2) Import Apache to eclipse
3) Install mysql
4) Download mysqlconnector/J
5) Unzip the zipped file navigate through it until you get the bin file in it. Then place all files that are present in the folder containing bin to C:\Program Files\mysql\mysql server5.1/
then give the same path as the address while defining the driver in eclipse.
That's all very easy guys.

If the problem still persists,
Put the-
mysql-connector-java-5.0.8-bin jar in a place inside your Tomcat->lib->folder (No matter where you've installed your Tomcat). And change your environmental variable (Done by clicking Properties of Mycomputer -Advanced system settings- Environmental variables-And set a new variable name & variable values as the place where your lib file resides.Dont forget to enter a ; at the end of the path)
If still problem persists
Try downloading commons-collections-2.0.jar (http://www.docjar.com/jar_detail/commons-collections-2.0.jar.html) and paste the jar in the same place where your mysql jar resides (ie) inside Tomcat-lib.
Clean your project-Stop your server- Finally try to run.

Many times I have been facing this problem, I have experienced ClassNotFoundException.
if jar is not at physical location.
So make sure .jar file(mysql connector) in the physical location of WEB-INF lib folder. and
make sure restarting Tomcat by using shutdown command in cmd.
it should work.

The only solution worked for me is putting the .jar file under WEB-INF/lib . Hope this will help.

assuming your project is maven based, add it to your POM:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.26</version>
</dependency>
Save > Build > and test connection again. It works! Your actual mysql java connector version may vary.

Put mysql-connector-java-5.1.38-bin.jar to the C:\Program Files\Apache Software Foundation\Tomcat 7.0\lib folder.by doing this program with execute

My issue was a little different. Instead of jdbc:oracle:thin:#server:port/service i had it as server:port/service.
Missing was jdbc:oracle:thin:# in url attribute in GlobalNamingResources.Resource. But I overlooked tomcat exception's
java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for connect URL 'server:port/service'

for this error:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
you need to:
Import java.sql.*;
Import com.mysql.jdbc.Driver;
even if its not used till app running.

How to import commons-io.jar jsp/java

I am getting an exception:
Cannot find symbol: FileUploadException;
I have a piece of code which uses
FileUploadException
The library that needs importing is:
org.apache.commons.fileupload.FileUploadException
The path to my project is :
D:\Projects\website
In the project folder I have each in its folder:
Tomcat, Derby, Website
I have copied:
commons-fileupload.jar and commons-io.jar
into both:
Tomcat/lib and Website/Web-INF/lib
---------------I tried this--------------
just importing the library on its own
import org.apache.commons.fileupload.FileUploadException;
adding the jars to the class path upon build:
javac -cp .;D:Projects\website\Tomcat\lib\commons-fileupload.jar;D:\Projects\website\Tomcat\lib\commons-io.jar com/otrocol/app/*.java
adding them to the Environment variables CLASSPATH
D:Projects\website\Tomcat\lib\commons-fileupload.jar;D:\Projects\website\Tomcat\lib\commons-io.jar
I also tried adding the jars where my .java files are as #Scot Ship suggested
----mentions---
I am not using any IDE
The code contains more unrecognized symbols, but I'm trying to solve one at a time
First time using apache, tomcat, jsp.. please be gentle

Vlad, the web container will automatically look for JARs inside
/WEB-INF/lib
even without any developer intervention. Take note that it's all caps WEB-INF. As long as your JAR is there, it will be in your web application's classpath.
Try to display this in one of your servlets or JSP:
System.getProperty("java.class.path")
and you'll get a better view of what classes and JARs were actually loaded.
Update: After reviewing your question, it appears you're facing issues in compiling the files to begin with and you're doing it outside an IDE.
Take note that when you use -cp in javac like this:
javac -cp .;D:Projects\website\Tomcat\lib\commons-fileupload.jar;D:\Projects\website\Tomcat\lib\commons-io.jar com/otrocol/app/*.java
Whatever value you have set in the CLASSPATH environment variable becomes ignored.
Be absolutely sure that the class FileUploadException is indeed inside one of the JARs you're trying to import: you can view the JAR directly using an unarchiving tool.
Also, change the com/otrocol/app/*.java to com\otrocol\app*.java - you should be using your system delimiter (not that this may affect your problem).
Create a simple HelloWorld in the same location as the file you're compiling, add the SystemOut mentioned above, and compile it the same way you're doing for the concerned file.

Read this http://commons.apache.org/proper/commons-fileupload/faq.html#class-not-found. Probably you have the fileupload jar but you also need commons-io.jar in your classpath as well.

Trying to Use ESAPI But getting Error

I am trying to use ESAPI.jar for providing security to my web application.Basically I have just started using ESAPI.jar.
But problem is I am not able to run even a simple program using ESAPI.
The small code snippet is:
String clean = ESAPI.encoder().canonicalize("someString");
Randomizer r=ESAPI.randomizer();
System.out.println(r);
System.out.println(clean);
I get this error:
Attempting to load ESAPI.properties via file I/O.

I have tried copying the 3 ESAPI properties files in my source folder and also configuring them on build path but still I have not succeeded. I have tried many permutations and combinations to no avail.
Please guide me.
The content of property file is:
# User Messages
Error.creating.randomizer=Error creating randomizer
This.is.test.message=This {0} is {1} a test {2} message
# Validation Messages
# Log Messages

The ESAPI.properties file should have more than 3 lines in it. See for example:
https://web.archive.org/web/20150904064147/http://code.google.com:80/p/owasp-esapi-java/source/browse/trunk/configuration/esapi/ESAPI.properties
In my experience the ESAPI.properties file either needs to be in the same folder as the esapi.jar or needs to be compiled into the jar in a resources directory.
/resources/ESAPI.properties
I believe that either one should work. If ESAPI does not find the file it one location it looks in others.
The code for that is here around line 620:
https://web.archive.org/web/20161005210258/http://code.google.com/p/owasp-esapi-java/source/browse/trunk/src/main/java/org/owasp/esapi/reference/DefaultSecurityConfiguration.java

I just struggled through this one myself.
I created a folder called esapi in my C:/users/myname/ directory and loaded up the ESAPI.properties, validation.properties, and the ESAPI-AccessControlPolicy.xml which got me past all the not finding files errors. ESAPI looks in several places for the files. I'm running Windows 7 64 bit by the way.
Then I had to update some of the jars. I should have done this from the beginning, but I didn't know it. I was getting this error:
AccessController class (org.owasp.esapi.reference.DefaultAccessController) CTOR threw exception.
for every jar that needed to be a newer version, like commons collections or log4j. At the bottom of the stack trace it would reference the offending jar.
When I added the newer jars from the esapi lib directory everything just worked!
I got this message at the end in my console:
ESAPI.accessController found: org.owasp.esapi.reference.DefaultAccessController#1cb8deef
Note: There is an ESAPI_en_US.properties file, but it's the one with only a few lines in it. Just use the file in: \esapi-2.1.0-dist\src\test\resources\esapi\ESAPI.properties. That is the full complete file.

After having this problem and looking at the installation documentation (esapi-x.x.x-dist\documentation\esapi4java-core-x-x-install-guide.pdf) I found a very useful section which detailed that the properties file can be anywhere, provided a vm flag (-Dorg.owasp.esapi.resources=path") points to a particular directory.
For example, if I stick the file in a "resources" folder at the root of my project directory, then the flag would be:
-Dorg.owasp.esapi.resources="path\to\project\root\resources"

The reference SecurityConfiguration manages all the settings used by the ESAPI in a single place. In this reference implementation, resources can be put in several locations, which are searched in the following order:
1) Inside a directory set with a call to SecurityConfiguration.setResourceDirectory( "C:\temp\resources" ).
2) Inside the System.getProperty( "org.owasp.esapi.resources" ) directory. You can set this on the java command line as follows (for example):
java -Dorg.owasp.esapi.resources="C:\temp\resources"
You may have to add this to the start-up script that starts your web server. For example, for Tomcat, in the "catalina" script that starts Tomcat, you can set the JAVA_OPTS variable to the -D string above.
3) Inside the System.getProperty( "user.home" ) + "/.esapi" directory (supported for backward compatibility) or inside the System.getProperty( "user.home" ) + "/esapi" directory.
4) The first ".esapi" or "esapi" directory on the classpath. (The former for backward compatibility.)

Can you put your file (with this name) in:
D:\Eclipse-Workspace\Test\ESAPI.properties
And show us the contents and exception again.

Extract the esapi jar
create a folder named resources under org.owasp.esapi
copy ESAPI.properties to the org.owasp.esapi.resources
Build and deploy

extract the jar
add properties file under resources folder.
initially getting same error, after updating properties file it worked for me

Thanks for providing the information
-Dorg.owasp.esapi.resources="path\to\project\root\resources"
This is a good source of information and has resolved my issue

I had the same problem too. I resolved it using a little bit of James Drinkard solution. What I basically did is created a new folder with name ESAPI and added ESAPI.properties file, Validation.properties, and the ESAPI-AccessControlPolicy.xml. And archived it into a jar file and added to the lib folder under WebContet/WEB-INF and build it to the path and it worked.
*To archive it into a jar file I used windows command move ESAPI ESAPI.jar

Look at the various scripts under 'src/examples/scripts' and they will show you one easy way to control where the ESAPI.properties files is found. (This is for ESAPI 2.0 or later.)
You will find a copy of the ESAPI.properties file will be under 'configuration/esapi'.
